THOMAS KITSON, OF STROUDSBURG, PENNSYLVANIA.

BLOWER.

SPECIFICATION forming part of Letters Patent No. 526,236, datedSeptember 18, 1894;.

App ic ti n filed September 3, 1892. Serial No. 444,972. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS KITSON, of

Stroudsburg, in the county of Monroe andan extremely simple and durableblower which is adapted to create a very strong draft, which may beapplied to any ordinary furnace without changing or renewing the grates,and the use ofwhich will enable a high and even steam pressure to bekept up 7 and cheap fuel to be used.

To these ends my invention consists ina blower, the construction ofwhich will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar figures of reference indicate corresponding partsin allthe views.

Figure l is a perspective view of the blower embodying my invention.Fig. 2 is a central longitudinal section of the same; and Fig. 3

is anenlarged detail sectional view showing the means of adjusting thesteam nozzle.

The body of the blower consists of a pipe 10, which has a bell-shapedend 11, and near the junction of the bell-shaped portion with the bodyis a flange 12, which strengthens the blower and facilitates itsadjustment in a support; and on the inside of the blower, opposite theflange, is a transverse support 13, having passages for the air throughit, this support being for the purpose of securing the inner end of thesteam nozzle 14, which nozzle extends centrally and longitudinally intothe pipe or body 10, the outer end portion of the nozzle beingheld in acentral boss 15, on the yoke 16, the latter being made to span centrallythe mouth of the bellshaped portion 11 and having at its ends lugs 17,which are bolted to similar lugs 18, on the bell-shaped portion 11.

The nozzle 14. is screw threaded on the part adjacent to the boss 15, asshown at 19' in Fig. 3, and this threaded portion fits a correspondinglythreaded portion of the boss, as shown clearly in Fig. 3, and by thisconstruction,

of any desired shape, but to give it the greatest efficiency its sidesshould approximate to the shape of the bell-shaped portion 11 of thebody 10.

The smaller end of the valve is thickened, as shown at 22, where itslides on the nozzle, and the larger end of the valve terminates in ahub 23, which fits the nozzle and which is provided with a set screw 24,adapted to impinge upon the nozzle, and by this means the valve may beheld in the desired position.

The operation of theblower is as follows:- The body portion 10 issecured in some suitable support so as to point and deliver into thedesired locality, and a steam pipe is coupled to the outer end of thenozzle 14. The steam rushes inward through the nozzle and into the body10, and the volume of steam creates a great suction which draws in theair around the valve 21 and the air and steam are delivered into orbeneath the furnace.

It will be seen that the valve 21 may be adjusted in and out so that therequisite quantity of air will pass through the bell-shaped portion 11and into the body 10.

Having thus described my invention, I'

claim as new and desire to secure by Letters Patent- 1. A steam blower,comprising a pipe having a bell shaped mouth,a nozzle extending throughthe mouth and held to deliver into the pipe, and a valve approximatelyconical in shape secured to the nozzle and held within the mouth, thesmaller end of the valve being placed inward, and the said valve beingadjustable in and out upon the nozzle, substantially as described.

2. A steam'blower, comprising a pipe having a bell shaped mouth, and astraight body portion, a yoke extending across the mouth, a transversesupport located within the pipe at or near the junction of the mouthwith the body portion, a steam nozzle extending into the pipe and havingits inner end secured to the transverse support and its outer end to theyoke, a conical valve held within the mouth and adjustablelongitudinally on the nozzle, and means for holding the said valve inposition, substantially as described.

3. A blower, comprising a pipe having a flaring mouth, a yoke extendingacross the mouth, a fixed support held within the pipe, a nozzle held insaid yoke and fixed support, and adjustable in and out in the pipe, anda conical valve secured to the nozzle and held within the said mouth andadjustable longitudinally on the nozzle, substantially as described.

4. A blower, comprising a pipe having a bell shaped mouth and a straightbody portion, a yoke extending across the mouth and provided with acentral boss having a screw threaded opening, a transverse supportwithin the pipe, a nozzle arranged centrally in the pipe, and having itsinner end held in the transverse support and having its outer end screwthreaded to fit the threaded portion of the boss, whereby the saidnozzle may be adjusted in or out, a set screw projecting through theboss and adapted to impinge on the nozzle, and a conical valve held toslide longi tudinally on the nozzle within the said mouth, the saidvalve having its sides shaped to ap proximately correspond to the wallof the mouth and having a hub at its outer or larger end provided with aset screw adapted to impinge upon the nozzle, substantially asdescribed.

THOMAS KITSON.
